Reading up on that in an article on a German magazine [1] clarifies that
the effort to create that hash still quite large (6500 CPU years + 100
GPU years to calculate the collision). So this relativates the impact a bit.
Certainly I'm not trying to say that the situation on SVN's side
should/could not be improved, though.
